Tengoku Daimakyo

Tengoku Daimakyo takes place after the world has collapsed and grotesque monsters roam the ruins of Japan. Survivors gather whatever they can to stay alive in the devastated landscape. Kiruko, an odd-job girl in Nakano, accepts a dying woman's mysterious request: escort a boy named Maru to a place known only as Heaven. Their journey begins in a world where even reaching that unknown destination means crossing dangerous territory.
